Hello, I am trying to set up a Nextcloud on my Ubuntu home server and connect it to my Namecheap domain.
I installed Nextcloud via snap and added my DOMAIN to the trusted domains. Generally, I followed this guide:
Now I tried to connect it to my DOMAIN after setting a host record with my server’s EXTERNAL_IP. However, connecting via the let’s encrypt method seems to keep failing.
Do I need any other certificates than explicitly adding the EXTERNAL_IP as a host record?

Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
